    The point is that a few months ago I noticed that my car will cost a little start in the morning, last month I changed the battery in Audi workshop and last thing has gotten worse, because now begins the third and start "tac,tac,tac" with the engine and white smoke from the exhaust. The rest of the day starts perfectly the first time and does not vibrate and smoke check. I pray you opinions and suggestions seriously, because I want to fix the problem before it gets bad weather, as I walk down hill.

    I know this is a widespread problem in the engines BKD, but I have not found a good answer on the solution.

    Thanks and regards.

    Incidentally, my cylinder head is 03G 103 308 B code and does not consume coolant.

    Yes, it can be. I hear a slow metal "tack, tack, tack" in the front before starting. But then, what about the much white smoke?

    Because the engine and oil are very cold (It hasn't been on to keep warm, and night time is coldest time), the starter motor has to work harder.

    In the day the engine and oil aren't as cold, and if the car has been on then they are warmed up, so the car will start easier.

    Hiya Mate
    Just to clarify does it only struggle to start on the 1st attempt in the morning? correct
    Do you get the strong diesel smell all the time or just in the morning? If its all the time and it smells like strong burning diesel it can be the glow plug module/glow plugs
    I had the same issue with my bmw 330d and turned out to be the glow plug module

    hmm..If its your starter motor best thing to do is when it struggles to start smack the starter motor and if the engine fires up then its defo the starter motor. If its not the starter motor i will Certainly have the glow plug/module inspected :uhm:

    Today I noticed that when I put the contact in the car at any time of day, appears briefly witness the heaters (orange spring). But in the morning, on first boot, car parks this witness never for a moment. Otherwise it would make sense right?. Do you think this may have something strange or should be?

    Today I discovered oil dry on the boards of the EGR valve and gas inlet butterfly. Any suggestions on this problem? I need an answer, thanks.
